`RAILWAY-DUMP-can cnufrn LOCK.'

application filed August 6, 1925. serial No. 48,5722.

The invention relates in general to railway dump `cars ofthe type in which the car bed is arranged to be tilted to one side or the other of the track to discharge its load and the present disclosure constitutes acompanion case with application entitled Air dump car chute, Serial No. 485521, tiled under even date (File No. 1307).

It is a usual practice as isl disclosed in the companion application to provide such dump cars with side aprons, extension pieces or chutes disposed along the side mar- .gins of the floorl of the bed and hinged thereto so that they mayl be swung laterally to form extensions of the floor to throw the material being unloaded out far enough from the track so that it is not `deposited on the track bed.' When the vcar body is in its normal position the side, aprons or chutes are withdrawn so that they do' not project beyond the side margins of the car bed and assume a substantially vertical position.

kIn the companion application there was featured a construction to permita limited rocking of the bed without swinging the apron or chute beyond the outline of the car body. `Such constructions, however7 have the objection in lthat Vthe depending apron or chute tends to swing laterally while the car is running and this lateral swinging of the heavy aprons on each side frequently ldevelop a synchronizing action' between the different parts witha resulting acquiring of a sldewise momentum which 1s very apt to deleteriously affect the car andv eventually rack it'to pieces.

kAccordingly, .thek primary object of the present disclosure isI to obtain the advantages of the apronV and chute construction featured inthe companion application in so far as s nnpliclty .of construction, ease ofoperation and the like are concerned, and, at the same time, to provide for the secur- 'ing ot the apron against swingingmovement when the car body is in its normal righted position.

Another object of the invention is to pro vide a simple rform* of construction by means of which the apronsV are automatically locked against swinging movement as an incidentof the movement of the chute intoy "sarily bemadeof heavy. construction in orand combination of der 'to withstand the strains to which such members are subjected itwouldfollowr that any lockingmeans for defeating atendency of these heavy members to swing must necessarily be rigid, massive and reinforced to provide a high strain resisting construction. Another Vobject of the invention is to provide a form of chute locking means capable `of` withstanding the heavy duty to WhCh one form of device embodying my invention, and the inventionv also consists in certain new and novel features of constructiony parts hereinafter set forth and'claimed.

Int-he accompanying drawings in which in the following particular description of there has beenillustrated vonly suchparts of Y the dump car as` are necessary to an understanding of theinvention, Figur-e l is a vertical cross section of a dumpcar to which the improvements herein featured are applied showing the normal position of the part-s in full linesl and in dotted lines their Vposition-when the bed :has been tilted to discharge the load to the right; and

Figure 2 is av detailed plan view looking ydown upon one end of the apron and showing Aits locking connectionwith the stop on the adjacent end sill.

, VIn the following description and in theclaims7 parts will be identified by specific vnames for convenience of expression but-` they are intended to be as generic in their application to similar parts as the art will permit.

Referring to the drawings l indicates the car'bed as a whole; 2 the yHoor thereof; and 3 and 4t the side gates. i,

The bedy is longitudinally mounted upon its lonofitudinal center line on a series of pivots i?? arranged at suitable intervals 'and' 'supportedzby standards ,8 mounted on the Vlos l elevating or the depressing movement of the car body/as' it is tilted to andfrom its dumping position. a if v -v VVliile I have shown and described, and have pointed out in the annexedclaims, certain novel features of my invention,fit will bey 'understood that various omissions, .substitutions and changes in' the forni and details ofthe device illustrated.. and in its operation may 4be made by those skilled in the art without departing from the spirit of the invention. j I Y Havingy thus ydescribed my invention, I claim f fl. In a dumpcar,thecombination with a car bed mounted to ytilt laterally to discharge its load and provided withl a side gate, of aside chute pivotally suspended `along a side marginl ofthe .bed ybelow the gater and adapted tol be projected 4into position to form a lateral extension. of the floor thereof, means actuated by the tilting of the bed to discharge its load toproject said chute into operative position andmeans spaced from the pivotal mounting of thetchute and operative on the righting of the car bedinto its normal position for automatically lockingl the chute inits suspended position toprevent swinging of the chute while the car is moving.v ,y o Y. f I
